BACKGROUND OF THE INVENTION 1. Field of the Invention

The present invention generally relates to the field of cleaning parts and, more specifically, to a method of cleaning and/or sanitizing jewelry and other small parts.

2. Description of the Prior Art

Precious stone and metal jewelry is at its most beautiful when perfectly clean and free from body oils, film, grime, and other deposits that can hide the shine, sparkle and character of the jewelry. Notwithstanding the desirability of maintaining jewelry in a very clean state, it is difficult to effectively clean jewelry.

The professional process of cleaning jewelry involves the following steps. First, the jewelry pieces are boiled in a concentrated cleaning solution for about 15 to 30 minutes. Next, the jewelry is removed from the concentrated cleaning solution and is rinsed with hot water. Lastly, the jewelry is subjected to high pressure steaming to quickly remove any remaining water to prevent spotting. While cleaning in this manner renders a piece of jewelry the benchmark 100% clean, the equipment, time, and steps involved in professionally cleaning jewelry is out of reach of the vast majority of consumers and even small jewelry stores with limited space. As a result, there have been attempts to devise less costly and involved devices and methods for cleaning jewelry. For example, liquid jewelry soaking solutions are available. A user will soak a jewelry piece for some time, and then attempt to brush away the grime. Results of about 30-50% are about the best achievable. Commercial ultrasonic jewelry cleaning machines are now being sold. However, these machines can only accomplish cleaning to about 70-80% clean. Also, most of these machines are bulky, heavy and costly. See U.S. Patent Publication Nos. 2013/0306111 to Myers; 2004/0040586 to Kumar and 2010/0186780 to Larocca et al for a dental appliance cleaning apparatus. See also, U.S. Pat. No. 9,339,852 to Campbell that discloses a cleaning device used to clean jewelry by heating clean water dispensed through jet nozzles to spray the jewelry while in a rotating basket.

U.S. Pat. No. 4,941,490 to Gross discloses a low temperature apparatus for cleaning jewelry. The Gross device delivers a low temperature mist of cleaning liquid and a stream of compressed warm air for drying the jewelry once it is cleaned.

U.S. Pat. No. 5,209,784 to Bellman discloses a method and apparatus for jewelry and small parts cleaning. In the Bellman method and apparatus, a large mesh basket with internal hooks posts and compartments is provided for placement in an automatic dishwasher, where the water and water laced detergent will be allowed to impinge on the jewelry pieces contained in the basket and thereby cause cleaning. According to Bellman, results of 80-85% cleaning of oil and dirt can be achieved using the patented method. While this range of results is comparable or better than that achieved with other available non-professional cleaning methods, it still falls short of the perfect results achieved by professional methods of cleaning, which leaves jewelry most brilliant.

Accordingly, there remains a need for a simple and easy to use method and kit for cleaning and/or sanitizing jewelry which achieves 95%+ cleaning results.

Known jewelry cleaning devices use sonic technologies, pressurized steam and other cleaning chemicals to remove or dissolve foreign substances from jewelry. These devices are largely for personal use.

More recent jewelry cleaning devices and methods are sonic cleaners, described in U.S. Pat. No. 6,719,850 issued to Glucksman et al. on Apr. 13, 2004, and U.S. Pat. No. 7,448,398 issued to Glucksman et al. on Nov. 11, 2008; steam cleaners, described in U.S. Pat. No. 6,129,097 issued to Edward Papandrea on Oct. 10, 2000 and U.S. Pat. No. 7,257,319 issued to Michael Clarke on Aug. 14, 2007; and a method describing a complete immersion in cleaning solution, without vibration, described in U.S. Pat. No. 6,076,538 issued to Jon Frankson on Jun. 20, 2000 and patents by others almost a half-century before that time.

U.S. Pat. No. 6,719,850 discloses a small, quiet, sonic cleaner where jewelry is immersed in a cleaning solution and vibrated in the sonic range. The patent also discloses the method for using the cleaner. The patent discloses hooks within the cleaning tank where jewelry can be fastened which rotate in response to the vibrations. U.S. Pat. No. 7,448,398 discloses an improvement over U.S. Pat. No. 6,719,850 in that it provides for removable tanks for ease of disposal and replacement of spent cleaning solutions. Both of these patents disclose machines that are primarily for in-home use.

U.S. Pat. No. 6,338,350 discloses a device which can be attached to a steam cleaning machine to clean jewelry. The device consists of a nozzle through which a jet of steam enters a closed mesh container that holds the jewelry being cleaned. The attachment is mounted to the steam cleaning machine through a support located at the open top of the neck portion of the attachment. This patent also teaches the use of tweezers through an opening in the mesh container which can be manipulated by the user to target the jet of steam onto the jewelry being cleaned.

U.S. Pat. No. 7,257,319 discloses a portable jewelry cleaning device that emits steam through a tube over the jewelry being cleaned. A containment device is optionally provided which catches any jewelry which is dislodged during cleaning. Unlike the disclosure in U.S. Pat. No. 6,338,350, this device houses a steam generator and is self contained. A water reservoir is also housed within the device which is filled by the user.

U.S. Pat. No. 6,076,538 discloses a jewelry cleaning kit and method wherein the user secures the jewelry in holding basket and dunks the basket with the jewelry into a cleaning solution. The basket with the jewelry is then placed in an automatic dishwasher for a final cleaning with a water spray and steam.

It has also been proposed to heat cleaning fluids, including water and cleaning solutions, by heating the same in a microwave oven. In U.S. Pat. No. 9,365,809 to Maiuri Cleaning Solution for Smoking Paraphernalia and Method are disclosed in which identified cleaning solutions, alone or diluted with water, are heated prior to being applied to a soiled surface for cleaning. The patent teaches placing the cleaning fluids or solutions in a microwave oven for different time periods to clean different tarnished surfaces, suggesting that the most effective temperature is approximately 180° F. The solution is then sprayed onto a soiled surface to be cleaned. It is suggested that different heating times ranging from 10-120 seconds in the microwave set on “high” for different solutions may be required to clean different levels of grime or soil surfaces using temperatures ranging from 120°-182° F. U.S. Patent 2005/0159326 to Holyworth discloses a Method for Cleaning Carpets and Other Surfaces by using a vessel containing a cleaning composition placed into a microwave oven and heated to a temperature of approximately 90-220° F. after which the heated cleaning composition is applied onto the soiled surface by a means of a spray dispenser.

In U.S. Pat. No. 2,141,713 to Hensler et al a machine is disclosed for cleaning jewelry that uses a mounting panel for supporting the machine on a vertical surface, such as a wall, including a motor secured to the panel. A vertical shaft of which extends downwardly to supporting a basket into which items to be cleaned may be placed. A non-heated cleaning solution is placed in a liquid non-circular shaped container and the basket is submerged in the cleaning solution, after the container is secured to the panel, so that the basket is positioned “off center” to produce a rotation of the cleaning solution to physically impinge against the items to be cleaned. This machine is not portable and cannot be used to sanitize the items to be cleaned. Furthermore, using a motor to rotate the basket requires access to an electrical outlet or hardwired connection to a source of electricity.

In U.S. Pat. No. 5,876,513 to Frankson a holding basket receives items to be cleaned. The basket is placed into a cleaning solution to coat the jewelry with the solution after which the basket with the items are placed into a dishwasher and run through wash and dry cycles that removes the cleaning solution and grime from the items in the basket. This solution requires a dishwasher, is clearly not portable and the effectiveness of cleaning will be a function of the temperature of the hot water supply delivered to the dishwasher. The mentioned temperatures of tap water heated to “below 120° F.” would not be adequate to sanitize the jewelry by the proposed method.

SUMMARY OF THE INVENTION

It is an object of the invention to provide a method of cleaning jewelry and small items or parts that is simple to use.

It is another object of the invention to provide a cleaning device that is portable and can be used anywhere.

DETAILED DESCRIPTION

Referring now specifically to the figures, in which identical or similar parts are designated by the same reference numerals throughout, and first referring to FIG. 1 a first major component of the cleaning device in accordance with the invention includes a generally cylindrical container 10 for receiving a fluid in a jar or tub 12. The container also includes a lid 14 that can be threadedly attached to the jar by means of conventional threads or other means. The details of the jar 12 and lid 14 will be described in more detail below. Besides the cylindrical container 10 another major component of the cleaning device is a spinning mechanism or carousel receivable within the jar 12, as to be described.

Referring to FIG. 1-1C the jar or tub 12 includes a generally cylindrical inner shell 12 a. An outer shell 12 b encloses the inner shell 12 a. The axial height of the inner shell corresponds to the height of the outer shell of the inner shell but includes an annular or cylindrical extension forming a threaded region. A circumferential grove 12 c is provided on the exterior surface of the inner shell 12 a. The upper edge of the outer shell 12 b is provided with an inwardly directed annular rim or lip 12 d preferably tapered to facilitate the rim to be snapped into the annular groove 12 c to retain the two walled members in place once assembled. An outer thread 12 e formed on the inner shell 12 a extension is conventional and configured to mesh with an inner thread 14 a (FIG. 1I) within the lid or cover 14. Preferably an inner marking 12 f is provided as shown in FIG. 1A to designate a maximum fill line for filling of a fluid such as water, a cleaning solution or a mixture thereof. As shown in FIG. 1A, the inner and outer shells 12 a, 12 b are configured to provide an inner space 12 g between the shells when assembled to provide thermal insulation to maintain the temperature of the outer shell 12 b comfortable to the touch when gripping the container during use as to be described. As shown in FIGS. 1A and 1D the jar 12 has a bottom wall and a top opening at opposing axial ends along the container axis A_(c). Provided on the bottom wall is a central raised portion 12 h with a central depression 12 i, that is shown in FIG. 1D. Provided around the central raised portion 12 h are integrally molded spaced upwardly projecting tabs or protuberances (FIGS. 1A and 1D) that will be further described in connection with FIG. 9I. Holes 12 j (FIGS. 1A and 1F) are formed in the bottom wall of the outer shell to allow any water as other fluid trapped between the inner and outer walls 12 a, 12 b to escape as well to prevent buildup of pressure between the walls when water or other fluid is heated in a microwave oven and turned into steam.

The cleaning device in accordance with the invention can be used with any fluids and cleaning solutions, with different degrees of advantage, at sanitizing and below sanitizing temperatures. However, best results and sanitation of the items to be cleaned are best obtained when the fluid or cleaning solution is heated to a temperature of at least 170° F. and preferably in excess of 170° F. Towards that end the inner and outer shells 12 a, 12 b may be formed of any suitable microwavable materials that can withstand these temperatures. Preferably, the inner and outer shells are formed of a plastic material, such as but not limited to a high temperature polypropylene. The inner and outer shells need to withstand the indicated temperatures without deformation or warping. Preferably, the thickness of the shells, the size of the insulating air gap or space 12 g are selected to render the outer shell comfortable to the touch even when the temperature of the fluid within the inner shell is heated to sanitizing temperatures. Preferably, the outer shell is provided with a series of circumferential or elongated depressions 12 k as shown in FIGS. 1A-1C to receive a user's fingers to provide reliable gripping of the container and prevent slipping thereof when removed from a microwave oven. Slip resistant feet 12L (FIGS. 1 a and 1F) are provided at the bottom of the jar or tub 12 to prevent sliding movements when the cleaning is operated as described with reference to FIGS. 9A to 9X.

Referring to FIGS. 1H and II, the lid 14 is provided with inwardly projecting santoprene tabs 14 b that serve as rests for the carousel as to be described. Rubber slip-resistant lands 14 c are provided on the other side of the lid when it serves as a base for the carousel on a countertop or other surface.

Referring to FIGS. 2-2B, a carousel or spinning mechanism 16 is a second major component of the cleaning device and includes a basket forming an annular tray 18 for supporting small items to be cleaned and dimensioned to be removably received within the jar 12, the basket defining a basket axis A_(b) that is substantially coextensive with the container axis A_(c) when the basket 18 is received within the jar 12. The basket 18 diameter is somewhat smaller than the inner diameter of the inner shell 12 a to maximize the size of the basket while providing a clearance with the inner surface of the inner shell to allow the basket 18 to rotate freely about the axes A_(c), A_(b) without contacting the inner shell. The basket 18 includes a lower transverse base 18 a and a generally cylindrical circumferential wall 18 b. Projecting upwardly, as viewed in FIG. 2 , from the base 18 a are circumferentially spaced upwardly directed projections 18 c and downwardly projecting generally radial circumferentially spaced fins 18 d.

The base 18 a is joined with an upwardly projecting central post or main body 20, preferably integrally formed with the base 18 a at the lower end thereof as shown. An annular recess 22 is provided in the region where the central post 20 meets the base 18 a. At the upper end of the central post or body 20, as viewed in FIG. 2 , the upper free end is formed with a downwardly projecting tubular or annular extension 24 and an upwardly extending tubular or annular portion 26. The tubular extension 24 has an internal diameter d₁ and the tubular extension 26 has an inner diameter d₂ where d₂ is shown to be greater than d₁. The tubular extension 24 is dimensioned to receive a spiral plunger 27 with clearance to allow the plunger to move axially up and down through the tubular extension while maintaining its central position along the axis A_(b). Provided along an upper edge of the annular or tubular extension 26 there are provided at least two sloping or inclined cam surfaces 20 a (FIG. 2G) symmetrically arranged in relation to the axis A_(b) to cooperate with a spin clutch 28 and having stop surfaces 20 b so that the clutch can slide along the inclined surfaces 20 a and be stopped by the stop surfaces 20 b. The spin clutch 28 is provided with an annular rim 28 a that has a diameter greater than d₂ and a number of outwardly projecting radial tabs 28 b, equal to the number of cam surfaces 20 a and stop surfaces 20 b. The clutch 28 is provided with a central rectangular slot 30 (FIG. 2F) having a length and width dimensioned to receive the rectangular cross-section of the spiral plunger 27 with small clearance to allow the plunger to freely move upwardly and downwardly through the rectangular slot 30 with minimal friction. A cup-shaped clutch cap 32 is fixed to the outer surface of the tubular extension 26 as shown to provide sufficient axial clearance “h” (FIG. 2 ) to allow the spin clutch 28 to move up and down in response to vertical movements of the plunger 27 to disengage the tabs 28 b from the cam surfaces 20 a (FIG. 3B) when the clutch is raised to bring the rim 28 a into contact with the cap 32 and engage the tabs with the cam surfaces when the clutch is lowered to bring the rim 28 a into contact with the portion 26 of the post 20. When the spiral plunger is pushed downwardly to urge the radial or lateral projections or tabs 28 b to slide on the cam surfaces 20 a into engagement with the stop surfaces 20 b to thereby engage and rotate the clutch and, therefore, likewise cause the central post or main body 20 to rotate when the spiral plunger is forced downwardly. When the spiral plunger 27 has reached its lower most position, as shown in FIG. 2 , it can be manually raised, causing the spin clutch 28 to be raised above the inclined cam surfaces 20 a formed within the upwardly extending tubular extension 26. Such engagement of the clutch allows the spiral plunger to be raised to an upper most position to again repeat the cycle by again pressing the plunger downwardly for continued rotation of the basket 18 by repeated engagement and disengagement of the clutch from the central post 20. Dots or small protuberances 28 c (FIG. 2E) are spaced along the rim 28 a that minimize small points of contact with the under facing surface of the cap 32 when the clutch 28 is in a raised position to ensure that the clutch does not stick to the cap when the plunger is in an extended position but drops when the plunger moves vertically downwardly.

Preferably, an inner tube 36 is provided, as shown in FIGS. 2, 2B and 2C that extends from the inwardly extending tubular extension 24 to a pivot plug 34 that includes a disc portion 34 a, an inwardly-directed central tubular extension 34 b, and central or axial downwardly-directed boss 34 c. The boss 34 c is a downwardly projecting protuberance preferably provided with a generally rounded or pointed end as shown. The disc portion 34 a is preferably adhered or otherwise affixed to the basket 18 at the annular recess 22. A compression spring 38 is positioned axially within the pivot plug central tubular extension 34 b and maintained centered by means of circumferentially spaced axial fins 34 d (FIG. 2K). The spring 38 engages the lower most end of the spiral plunger 27 when it reaches its lowermost position to initiate an upward movement of the plunger. The elements or the components described in conjunction with FIG. 2 will be defined or denominated as a spin mechanism. The spin mechanism is generally similar to the spin mechanisms used in toy spinning tops and operates substantially in the same way.

Spinning the basket 18 on the boss 34 c within the jar 12 filled with a fluid, aided by the radial fins 18 d, will create a degree of turbulence within the fluid especially if the basket is caused to rapidly rotate relative to the fixed container jar 12, resulting in mechanical removal of debris and contaminants from items placed on the tray of the basket 18.

Depending on the nature and properties of the fluids or cleaning solutions used spinning of the carousel can also help to neutralize some or most contaminants. In a presently preferred embodiment of the invention there is also provided a metal disc 42 with circular holes 42 a (FIG. 2N) dimensioned and arranged to receive the circumferentially spaced projections 18 c on the basket 18 to rotate therewith. Preferably, the metal disc 42 is also provided with an array of additional distributed holes 42 b to increase its surface area. Selection of an appropriate cleaning fluid in conjunction with an appropriate metal disc 42 can be effective both at ambient temperature or at an elevated temperature, with different degrees of advantage. Preferably, the container with the fluid is heated in a microwave oven to a temperature of at least 170° F. and preferably above 170° F. The cleaning solution advantageously includes a relatively strong base, such as sodium carbonate that dissolves and ionizes in water, acts as an alkaline that disassociates into the weak carbonic acid and a stronger alkaline sodium hydroxide. The sodium carbonate solution provides the ability to attack metals such as aluminum with the release of hydrogen gas. The release of hydrogen gas provides a second or additional mechanical mechanism for dislodging dirt and surface contaminants from metal parts placed within the tray or basket 18. The sodium carbonate is also useful as an electrolyte that acts as a good conductor in the process of electrolysis, creating carbonate ions that allows a small electrolytic current to flow. Hydrogen ions produced by this reaction reduce sulfide ions, for example, restoring silver metal. Disc 42, therefore, should be formed of a relatively active metal with increased ability to oxidize, such as aluminum, zinc, and nickel that can clean reducing metals that have the ability of being reduced, such as silver, platinum and gold. The oxidation reaction, for example, drives the reduction of silver. In this case, aluminum is an oxidizing agent reducing silver sulfide to elemental silver while forming aluminum sulfide. A heated fluid or liquid, such as boiling water, with or without an ionizable salt, increases the reaction when the solution temperature is higher. Aluminum in pure water would not remove silver tarnish because there is a film of aluminum hydroxide that stops the oxidation reaction. Sodium bicarbonate removes the surface film of aluminum hydroxide by dissolving it to expose fresh metallic aluminum ready for oxidation. Dissolving the sodium bicarbonate also increases the ionic strength of the solution, which increases the rate of the reaction.

Referring to FIGS. 2J and 2K, details of the pivot plug 34 are shown including the disc portion 34 a and the tubular extension 34 b. The central boss or protuberance 34 c extends in a direction opposite to the direction of the tubular extension 34 b and is provided with a pointed or rounded end 34 c suitable for point contact to minimize friction when spun or rotated on the bottom wall or central raised portion 12 h of the jar 12, when received and supported within the central depression 12 i. At least three spring centering fins or tabs 34 d are provided at the inner end of the tubular extension 34 b as shown.

Referring to FIG. 2I the spiral plunger 40 includes a flat upper end 40 a and a flat bottom end 40 b, and an operative spiral portion 40 c therebetween. A handle 40 d is fixed to the upper end 40 a and preferably provided with a finger grip with insulating pads 40 e. A transverse radial disc portion 40 f serves both to protect the user's hand from potentially hot cleaning fluids as well as for supporting opposed downwardly extending axial arms 40 g each of which includes an inwardly directed radial locking tab or finger 40 h. The arms 40 g and fingers 40 h are configured and dimensioned to be selectively receivable within diametrically opposite surface or exterior axial grooves 32 a in the cap 32, when moved downwardly, and circumferential grooves 32 b, when rotated relative to the spin clutch cap 32 to provide a bayonette-type connection to quickly and easily selectively lock the spiral plunger 27 to the central post or main body 20 or disengage it therefrom (FIG. 3A). The disc portion 40 f is advantageously provided with markings 40 i and 40 j (FIGS. 2I and 3A) that respectively indicate to a user the clockwise and counter-clockwise rotations of the finger-grip 40 e to lock and unlock the plunger assembly 40 to or from the spinning mechanism or carousel 16.

Referring to FIGS. 2L and 2M a small part stabilizer 44 is shown that is generally disc shaped and dimensioned to be received within the tray of the basket 18. The stabilizer 44 includes a generally circular disc or platform 44 a most of which is porous (e.g. mesh 44 b) and includes somewhat tapered axial projections 44 c dimensioned to frictionally engage the central post 20 along different axial positions along the post to accommodate jewelry or other small parts of different sizes by wedging the items to be cleaned between the disc or platform 44 a and the tray of the basket 18. The axial projections 44 c may be somewhat flexible and inwardly inclined to expand when placed over the post in frictional engagement. Jewelry or small parts are placed on the tray of the basket 18 directly or on the metal 42 disc. The stabilizer 44 is moved downwardly until there is contact between the stabilizer 44 a and the items to be cleaned to prevent movements of the items to be cleaned when the basket 18 is rotated. The parts to be cleaned are maintained fixed on the tray as it rotates and the fluids impinge against the items to be cleaned. This is enhanced by providing radial fins 44 d that promote agitation of the fluid.

Referring to FIG. 2O, a cleaning and resurfacing disc 54 may be used to resurface the disc 42, being provided with a finger grip 54 a and a disc 54 b provided with an abrasive surface (not shown) on the disc 54 b.

The rinse bubble 46 and small parts stabilizer 44 are accessories that will be used as may be needed at user's discretion. This will depend on the size and type of the jewelry being sanitized and rinsed. The link website of Jewelry Spa Hot Tub provides additional details, instructions and examples to help a user decide what steps or accessories to choose for a given task.

Referring to FIGS. 4A and 4B, a rinse bubble 46 is shown, preferably made of transparent plastic. This is generally dome-shaped with a central opening 46 a, dimensioned to receive central post or body 20, to cover the tray or base 18 a and any objects thereon to be cleaned. A lateral opening 46 b is provided dimensioned to receive a sink sprayer attachment to rinse off any chemical or cleaning solution residues on the jewelry to be cleaned without splashing water beyond the rinse bubble.

Referring to FIGS. 5A and 5B a safety strainer 48 is shown dimensioned to be placed over and having a portion thereof 48 a fit within a drain of a sink. The circular strainer has a base formed of a meshed material 48 b that allows the plunger mechanism to be removed from the jar 12 and securely positioned over the safety strainer with the rinse bubble in place. This allows a jet of water to be sprayed through the lateral opening 46 b onto the parts to be cleaned and the water drained directly through the mesh 48 b at the bottom of the basket and through the safety strainer without the danger of any jewelry or any small parts to be dislodged from the basket 18 and dropped and lost in the drain.

Referring to FIGS. 6A and 6B, a jewelry brush 52, made with Santoprene TPV rubber bristles 52 a, has many uses as with any brush except it will not scratch shiny surfaces that are used in most all jewelry finishing. The tail or pick 52 b is designed to dig out dirt and grime that has been softened by the cleaning device during the sanitizing step that has hardened and may need some help being removed. The construction of the handle is polypropylene strong also safe to gems and the metals that will be sanitized.

FIG. 7 is an exploded view of the spinning mechanism or carousel 16 with a metal disc 42, a small part stabilizer 44, a rinse bubble 46 and a plunger assembly 40 positioned over the safety strainer 48.

Another feature of the invention is to form the outer shell 12 b of the jar 12 with a thermochromic material that will change the color of the outer shell in response to attaining a predetermined temperature. The specific thermochromic material used is not critical. However, it should be selected to change light reflection, absorption and/or scattering properties at a predetermined temperature of a liquid heated in the jar 12 placed in a microwave oven (e.g. at 1200 watts) so that the color of the outer shell 12 b can be a solid color, such as blue, when the liquid or cleaning solution is at ambient temperature, such as 72° F. After one minute or two minutes, for example, when the temperature reaches approximately 139° F. the outer shell 12 b starts to change colors to a light blue with some white regions and after 2-3 minutes when the temperature of the cleaning fluid achieves sanitizing temperature of at least 170° F. the outer surface of the outer shell 12 b turns substantially white over the entire visible area. This provides a visual indicator that the fluid or cleaning solution has reached its sanitizing temperature and the container may be removed from the microwave oven and can receive the carousel 16 with the basket 18 and the jewelry or items to be cleaned together with the plunger spinning mechanism for rotating the basket 18 within the heated cleaning fluid.

Referring to FIG. 8 , a portable cleaning kit 50 in accordance with the invention includes the following elements or components, some of which may be optional (as noted):

-   -   1. A container 10, including ajar 12 and a lid 14;     -   2. A spinning mechanism or carousel 16, including a basket 18;     -   3. a metal disc 42;     -   4. A small parts stabilizer 44;     -   5. A rinse bubble 46;     -   6. A safety strainer 48;     -   7. An optional combination brush and pick 52 (FIGS. 6A and 6B);     -   8.

The use and operation of the device will now be described.

-   1. The cleaning solution is prepared in accordance with directions     of the manufacturer. One solution suitable for use is distributed by     Jewelry Spa HOT TUB Inc., of Nyack, New York under the trademark     “JEWELRY SPA”® and “HOT TUB”™. -   2. Fill the jar 12 halfway to top with room temperature tap water. -   3. Add recommended amount of cleaning solution. -   4. Top off with tap water to the maximum fill line 12 f. -   5. Place sink safety strainer/caddy 48 over a kitchen sink drain     before attempting to use the container. This will allow only water     to drain and guard against any parts dropping into the drain. -   6. Place the lid counter or caddy 14, top side down, on a kitchen     counter next to the sink or other surface where the device will be     used. -   7. Place the complete spin mechanism or carousel 16 on the lid or on     the counter caddy 14. The lid 14 doubles as a work station drip tray     for the carousel during operation. The four protruding santoprene     rests 14 b will grip and keep the basket from spinning thereby     allowing the handle 40 d to be easily removed or reinstalled to     prepare for the Sanitizing or Rinsing steps. -   8. The spin handle is designed to be a one handed operation. Remove     the handle. With the handle off remove the rinse bubble and small     part stabilizer leaving the metal disc 42 in place. -   9. Place the rinse bubble 46 and small part stabilizer 44 aside as     these will possibly be required during the rinsing step. -   10. To remove the handle 40 d completely with the jar 12 positioned     on the lid or counter caddy 14 to steady it, press handle down then     twist the handle counter clockwise (FIG. 9A) to unlock. Then pull     straight up and out of the central body or post 20 (FIGS. 9B and     9C). -   11. To reinstall the plunger 40 place the lower flat portion 40 b of     the spiral shaft of the handle into the top of the central body or     post 20 and rotate until received through the rectangular slot 30     and let the spiral shaft drop under its own weight. It will drop     spinning down into place. Twist counter clockwise until the locking     tabs line up and gently push down (FIG. 9D) then twist clockwise to     re-engage lock. The basket 18 can be maneuvered with one hand into     or out of the jar 12 or during the sanitizing or rinse operation     etc. -   12. Place the item or items to be cleaned and/or Sanitized into the     basket 18 lying them on the metal disc 42 (FIG. 9E). Larger heavier     items will steady themselves. However, with smaller light weight     jewelry like diamond studs, thin chains etc. small part stabilizer     44 can be used at this time (See FIG. 9F). Or both the small parts     stabilizer 44 and the rinse bubble 46 can be used for maximum     security (FIG. 9G) This will keep the small Jewelry steady while     spinning the basket 18 as the items are sanitized or rinsed. -   13. Place handle back into the central body or post 20 and lock into     lifting position for rinsing, storage etc. (FIG. 9H). The     configuration of the device can be tailored for the individual type     of jewelry to be cleaned. -   14. One item or multiple items can be sanitized according to the     types of Jewelry and what can fit in basket. In depth videos can     also be viewed at the website of Jewelry Spa Hot Tub. -   15. The jar is placed into a microwave oven. The insulating outer     sleeve or shell 12 b turns white as sanitizing temperature is     reached. When sanitizing temperature is reached allow the jar to sit     for 30 to 60 seconds then carefully remove the jar and place it on a     kitchen counter or other surface where the user will be working.     Heat up time results may vary. The following Table is based on a     fresh 12 oz. bath filled to the MAX fill line 12 f in the jar 12 at     room temperature of 72° F. CAUTION should always be used when     heating and removing anything hot from a microwave oven. A safe     approach to avoid overheating is to start any of the recommended     heating time shown at 1.00 minute 30 seconds and increase in 30     second increments until a sanitizing temperature of 170° F. or     higher is reached. See below example color change chart.

-   16. The carousel 16 is now ready to be submerged into the jar 12. -   17. Using one hand tilt the entire basket towards the side wall of     the jar (FIG. 9I). There are stops 12 m molded at the bottom of the     inner shell 12 a that help steady the basket 18 in order to unlock     the spin handle 40 d. Press down on the handle and pivot to the left     to release the spin handle. -   18. Once released tilt the basket 18 back to the center along the     axis A_(c) of the jar 12 (FIG. 9J) and pull up handle (FIG. 9K) and     then more forcefully push down (FIG. 9L) spinning the basket slowly.     Repeat for 30-60 seconds.     When pumping the handle up and down only move the handle halfway so     the locking tabs will not hit on the locking cap. The basket can     also be allowed to sit and soak for 30-60 seconds. Repeat sanitizing     step as necessary. -   19. To setup for rinse, lock the spin handle 40 d in the lifting     position (FIG. 9M) and remove the dipping basket 18 out of the jar     12. At this point there are two options for rinsing.     a) The dipping basket 18 can be placed back onto the lid or counter     caddy 14, (FIG. 9N) remove the handle completely, leave the small     part stabilizer in place (if used) (FIG. 9O) and place the rinse     bubble 46 back into position over the basket 18 (FIG. 9P), replace     the handle and lock it in the lifting position then place on the     sink safety strainer for rinsing.     b) The carousel can be removed from the jar 12 and placed on the     sink safety strainer caddy 48 for Rinsing (FIG. 9T). -   20. Place the carousel onto the sink safety strainer/caddy 48     positioned over the drain earlier. The carousel is designed to sit     securely on the strainer caddy. Turn on the faucet to apply hot tap     water (jewelry should always be rinsed using hot tap water to avoid     thermal shock to gemstones that are known to be prone to this). Now     using the sink sprayer position over or directly into the lateral or     side opening 46 b in the Rinse Bubble 46 and spray the cleaned parts     (FIG. 9S). If the sink is not equipped with a sprayer the basket 18     can be held under the faucet spout (FIG. 9Q). For larger jewelry it     is not necessary to use the small part stabilizer or the rinse     bubble, the jewelry should be heavy enough to stay in place while     using either rinsing procedure (FIG. 9R). -   21. Place the dipping basket 18 back onto the lid and counter/caddy     14 (FIG. 9T) and allow to cool as rinse water drains. Excess water     can also be removed by spinning the basket while sitting on the lid     or counter caddy 14 (FIG. 9U). Then the rinse bubble, small part     stabilizer can be removed, if used, and finally the jewelry can be     removed. The jewelry can be patted dry with a paper towel. If some     imbedded grime is still visible the brush/pick 52 (FIG. 9V) can be     used to assist, or the above steps can be repeated. -   22. The jewelry should always be cleaned in the container 10 before     using the polishing cloth 58. Doing so will remove contaminants that     may be abrasive and will attach to the polishing cloth. Bypassing     the cleaning and rinsing steps will result in scratching the highly     polished surface of the jewelry during polishing. -   23. The polishing cloth 58 (e.g. the polishing cloth in the kit     supplied by Jewelry Spa HOT TUB Inc.) is laid down on a flat surface     (FIG. 9W), either side does not matter. Then with smooth even     strokes slide the jewelry back and forth. This will help in     brightening the high spots on the jewelry where it tends to become     dulled by wear. -   24. Pick up the jewelry and wrap it in the cloth (FIG. 9X) to get     into some of the other areas that may need additional shine. A paper     towel can be used to finish wipe.

An approved Testing Laboratory with Good Lab Practices (GLP) tested the device and method and found that the cleaning device 10 is effective in cleaning and/or sanitizing items of jewelry and removing the following representative test organisms: Staphylococcus aureus, Salmonella species, Escherichia coli and Pseudomonas. Testing was performed by filling the container 10 with approximately 3 oz of room temperature tap water and adding half bottle (3 oz) of a suitable solution concentrate that can be heated in a microwave oven to a temperature in excess of 170° F. Tap water was added to top off to tub fill line 12 f. The container 10 was then placed in a microwave oven. Initially, the microwave oven was set to high for 1 minute 30 seconds and extended by 30 second increments until the sanitizing temperature of 170° F. was achieved. As a visual aid, the tub or container changed color from blue green to white once the proper temperature was reached. The temperature was verified with a thermometer. The heating times/microwave wattage chart was referred to as a guide. Once the proper time was determined for the microwave unit, the same time was used for all subsequent heat ups. After sanitizing temperature was reached, the container or tub was allowed to stabilize in the microwave for an additional 30-60 seconds to avoid potential splash over or spillage.

When exposing the inoculated jewelry to the system of high pH solution and an average temperature of 177° F. for 30 seconds with mechanical agitation, all bacteria present was removed by the process leaving the jewelry bacteria free based on the criteria present in the protocol. When exposing the inoculated jewelry to the system of high pH solution and cold temperature of 76° F. for 30 seconds with mechanical agitation, all bacteria present was also removed by the process leaving the jewelry bacteria free based on the criteria present in the protocol.

On the basis of testing and observations it is clear that the device can be used to clean jewelry and small parts by removing surface contaminants including oils and dirt, sanitizing the surfaces and/or both. Oil, dirt and other surface debris/contaminants can be effectively dislodged and removed by mechanical means including turbulence or agitation of the cleaning fluids in which the jewelry or other parts are immersed and generation of chemical by-products such as generation of gas bubbles in and around the metal disc 42 on which the parts are supported. Heating of the cleaning fluids promotes the process by accelerating chemical reaction release of gases as well as softening surface contaminants that may also harbor embedded pathogens when heated as described the surfaces can also be effectively sanitized.

The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
